[SOLVED]Requires installation of untrusted packages "The action would require the installation of packages from not authenticated sources."

Requires installation of untrusted packages
"The action would require the installation of packages from not authenticated sources."

These words made me tensed for three more days because this message is often appeared in your software center or with your synaptic. I thought I have too reintall the os to resolve this. but this problem can be solved by executing a single line command in shell.

I've had some kind of trouble with updating since late in the use of 11.10 and hoped it would be resolved with the upgrade to 12.04. It has continued to be patchy. Finally this week, it just stopped completely with the error above.

I tried your suggestion and it repaired the keys (which may have been the original problem), but the update still produced the same error.

I went into recovery mode and tried dpkg to repair broken packages. It failed because it had trouble connecting to the internet, but suggested:

apt-get update --fix-missing

I re-entered Ubuntu and ran that successfully in the terminal. Then I ran the update successfully.

Thank-you for your assistance and hope, because I was very close to a re-install!
